OKLAHOMA CITY -- (KFOR) -- Ruthi Mason said she can’t figure out why anyone would want to hurt her daughter and grandson.

“There’s absolutely nothing that she would have done aside just existing that somebody would want to kill her,” Ruthi said.

Julie Mason, 41, and her son, Keagon Bruce, 8, were pulled from their burning home on N.W. 80th near Western in the early morning hours of December 17.

Julie was already dead, and Bruce was pronounced dead at the hospital.

Investigators said someone attacked them before setting fire to the house.

According to the medical examiner’s report, they both suffered blunt force trauma.
